Jim's Beer Kit

… What are you doing to your scales? The current ones switch on or off for no reason. I'm a bit worried that they didn't return usable results compared to my kitchen scales that have100x less resolution. Things got a little better when I stopped storing it in it's box (i.e. let the air circulate ar...

I have not long posted something that would be relevant to this thread: A very stylised illustration of a BIAB system … Click the little arrow after "PeeBee wrote:" to go to that post (if you are viewing via a mobile phone, you may not have the "arrow"). 64.4C is only a conversion from Fahrenheit, 1...

A very stylised illustration of a BIAB system (I've repurposed some earlier illustrations) might go like: BIAB.jpg The "Bag" containing the grain is immersed in a boiler, which has a tap, a heating element (E) and a temperature probe (T). The probe is probably part of something like an "Inkbird" ITC...

Least we forget (!): This is "Brown Beer's" thread, and I have together the ingredients to copy his intended beer: Melyn BS.JPG And the water calculations by MME: Melyn MME 8.35.JPG I'll try to put up an illustration of water calculations using MME for "Brown Beer's" supply. That should be a shock a...

… Surely your calcium chloride was 'usable' for brewing levels of accuracy in the first place? Yes, you may end up under-dosing it in some cases, but I doubt that would be to a degree that is going to make a noticeable difference in your final beer... unlike the levels of magnesium/sodium you might...

… I just discovered an easy way to drop this formula into a spreadsheet without ever needing to touch the formula itself. … That worked. And without my head going numb with all those numbers: Capture.JPG (This in Excel). 99.2262g anhydrous CaCl2 per litre (actually used 66.25g of supposedly "dihydr...

Right! I'll switch to home-brewer mode and use what's in the kitchen. Kitchen scales, 1 gram resolution but reads up to 2Kg. Plastic measuring cylinder (once for hydrometer) 250ml mark (fairly accurate, weighing-scales confirm 250ml water weighs 250g). Using these, bottle of prepared CaCl2 solution ...

Of course, sorry.

"Intertek"! My partner works for them. I had to get her to remind me those bottles with a hole in the stopper are called "pyknometers".

<EDIT: The spelling is debatable, but you also see the spelling "pycnometer", but hard "c" please.>

14.9 Brix = 1.08033 S.G. Try hitting it with your hydrometer again. Thanks. I hadn't suspected my refractometer had gone out of calibration. But all the information I can find puts 14.9 BRIX as SG 1.060-61? So the refractometer can join the hydrometer in the bin. Actually, I did give the hydrometer...

… That aside: Tried my refractometer on my SG1.072 CaCl2 solution and got 15.2. That was done a bit slap dash so I'll give it another go later. Very carefully repeated the refractometer reading, twice. I've known from use that the glass slide and cover need to be very clean. But both times I got li...

Loving this thread. Steadily getting more like 'Alice through the Looking Glass'!! Hope the OP's water analysis from Wallybrew turns up soon so we can get back on track! Guy This white rabbit sitting next to me thinks you are talking rubbish! Anyway, getting (just slightly on track) Malt Miller del...

… "Silver_is_Money"; If you are worried that I'm criticising your work, here's an example of me really criticising your work for comparison: You could take a Brix scaled refractometer reading of it: Grams of CaCl2 per Liter of solution = 5.9392*Bx + 0.050098*Bx^2 -0.00018856*Bx^3 + 4.7399e-06*Bx^4 (...

I've double checked the 'MME' formula for computing CaCl2 addition quantities via S.G., and I find no fault in it. PeeBee, are you finding it at fault? To give credit where credit is due, the formula I'm using in 'MME' was developed by A.J. deLange. Finding fault? Certainly not. I thought I was bei...

Thanks "Silver...", things like that are always better coming from someone else and not me <- loon-ey! ... hoy, shutup you . So in figuring out my own nonsense I try to look up an SG table for CaCl2 "brines". Surprisingly difficult, but this seemed okay: https://www.oxy.com/OurBusinesses/Chemicals/P...
